Wheel lug torque pattern
Always tighten wheel lug nuts in a star or cross pattern. This ensures even clamping force and prevents wheel hub distortion.
Brake torque notes
Brake caliper bracket bolts are critical fasteners. Always use a calibrated torque wrench and follow the manufacturer's procedure. Some bolts may require a thread-locking compound.
Why torque matters
Proper torque is critical for safety and reliability. Under-torqued fasteners can loosen over time, while over-torqued fasteners can strip threads or damage components. Always use a calibrated torque wrench for critical fasteners.
Disclaimer: These torque specifications are for reference only. Critical fasteners should always be verified in the OEM service manual.
